Let me be honest with you—if someone had told me before becoming a dad that I’d spend more time googling “baby sleep routines” at 3 AM than I ever spent researching anything in my life, I would’ve laughed. But here we are.Especially when dealing with challenges like the 4-month sleep regression, which can turn everything upside down overnight.
The thing about baby sleep is that everyone has an opinion, every book promises a solution, and yet, somehow, your baby didn’t get the memo. After months of trial and error, sleepless nights, and more cups of coffee than I care to admit, I’ve learned something crucial: there’s no one-size-fits-all solution. But there are things that work, things that absolutely don’t, and things we’re still figuring out.
If you’re reading this at some ungodly hour while your little one refuses to sleep, know that you’re not alone. This is our journey through the chaotic, exhausting, and occasionally triumphant world of establishing a baby sleep routine.
The Reality Check: What Nobody Tells You About Newborn Sleep
When our baby first came home, I had this naive belief that babies just… slept. After all, that’s what everyone jokes about, right? “Sleep when the baby sleeps!” they said. What they didn’t mention was that newborns sleep in 2-3 hour bursts, waking constantly to feed, and have absolutely no concept of day versus night.
During those first few weeks (0-8 weeks), we weren’t trying to establish any sort of routine. We were in survival mode. Our baby slept anywhere between 14-17 hours a day, but it was scattered across short naps with feeding sessions every 2-3 hours. The NHS confirms this is completely normal, though it doesn’t make those sleep-deprived weeks any easier.
What we learned during this phase:
- Trying to force a schedule on a newborn is pointless
- Day-night confusion is real and brutal
- Your baby will sleep—just not when you want them to
The key realisation? This phase is temporary. We weren’t failing as parents; we were simply living through the newborn fog that every parent experiences.
Our First Attempt: The Bath-Feed-Sleep Routine (And Why It Half-Worked)
Around week 6, we decided to try establishing our first proper bedtime routine. We’d read everywhere that consistency was key, so we created what seemed like the perfect plan:
- Warm bath at 7 PM
- Baby massage with coconut oil
- Fresh nappy and pyjamas
- Feed
- White noise and swaddle
- Put down drowsy but awake
What worked:
The bath genuinely seemed to relax our baby. That post-bath drowsiness was real, and the warm water became a clear signal that bedtime was approaching. The white noise machine was also an absolute game-changer—we use it to this day.
What failed spectacularly:
The “drowsy but awake” part. Every parenting expert swears by this, but in practice? Our baby would either be fully awake and screaming the moment we put them down, or so drowsy they were basically asleep (at which point, why risk waking them?).
The feed-before-bed also created an association we’d later struggle with. Our baby started to rely on feeding to fall asleep, which meant every time they woke during the night (which was often), they’d need to feed to go back down.
The 3-Month Mark: When Things Started to Click (Sort Of)
Something shifted around 12 weeks. Our baby’s sleep cycles began to mature, and we could see patterns emerging. They started taking longer stretches at night—sometimes 4-5 hours, which felt like a luxury—and their naps became slightly more predictable.
Our adjusted routine at 3 months:
- 6:30 PM: Start winding down (dimmed lights, calm environment)
- 6:45 PM: Bath time (not every night, but most)
- 7:00 PM: Pyjamas, sleep sack (we’d transitioned from swaddle)
- 7:15 PM: Feed in a quiet, dark room
- 7:30 PM: Cuddle time with lullaby
- 7:45 PM: Into the cot with white noise
At this stage, we were getting about 3-4 naps during the day, each lasting 30 minutes to 2 hours. We learned to watch for sleep cues—eye rubbing, yawning, that glazed look—rather than sticking rigidly to a clock-based schedule.
What worked:
- Starting the routine earlier (6:30 PM instead of 7 PM)
- Keeping the environment consistently dark and calm
- Using the same lullaby every night (it became a powerful sleep cue)
- Making sure our baby wasn’t overtired by bedtime
What we were still struggling with:
- Multiple night wakings (usually 2-3 times)
- Short naps during the day
- The dreaded 4-month sleep regression looming on the horizon

The 4-Month Sleep Regression: Our Lowest Point
I’d heard horror stories about the 4-month sleep regression, but nothing prepared me for the reality. Almost overnight, our baby who had been sleeping in decent 4-5 hour stretches started waking every 60-90 minutes. Every. Single. Hour.
This regression isn’t just a myth—it’s a real developmental change where your baby’s sleep cycles mature and become more like adult sleep patterns. The problem? They haven’t yet learned how to transition between sleep cycles independently.
What we tried during the 4-month sleep regression (some successfully, some disastrously):
The failures:
- Rocking until fully asleep and transferring (they’d wake immediately)
- Letting them cry for “just a few minutes” (turned into 45 minutes of everyone crying)
- Changing the entire routine in desperation (consistency matters, even during regressions)
What actually helped during the 4-month sleep regression:
- Maintaining our bedtime routine religiously—no matter what
- Extending wake windows during the day (we realised our baby was undertired)
- Ensuring adequate daytime calories so night feeds weren’t about hunger
- Taking shifts with my partner so we each got some consolidated sleep
- Accepting that this was temporary (it lasted about 3 weeks)
The 4-month sleep regression was brutal, but it forced us to really understand our baby’s sleep needs. We couldn’t just copy someone else’s schedule; we had to tune into our specific child.
The Turning Point: What Actually Started Working
Around 5.5 months, something magical happened. No, our baby didn’t suddenly start sleeping 12 hours straight (anyone who claims that either has a unicorn baby or is lying). But we found a rhythm that worked for our family.
Our refined routine (5-8 months):
Daytime:
- Wake: 7:00 AM
- First nap: 9:00 AM (1-1.5 hours)
- Second nap: 12:30 PM (1.5-2 hours)—this became our “sacred” long nap
- Third nap: 4:00 PM (30 minutes—sometimes we’d skip this if the earlier naps were long)
Bedtime:
- 6:15 PM: Dinner (once we started solids)
- 6:30 PM: Bath time
- 6:45 PM: Pyjamas and sleep sack
- 6:50 PM: Quick feed
- 7:00 PM: Cuddles and lullaby
- 7:10 PM: Into cot awake
- 7:15-7:30 PM: Asleep
What made the difference:
1. Wake windows became our secret weapon
We stopped trying to force naps at specific times and instead focused on age-appropriate wake windows. At 5-6 months, that was roughly 2-2.5 hours between naps. This single change reduced bedtime battles dramatically.
2. The “long nap” priority
We made the lunchtime nap sacred. If it meant staying home instead of running errands, we did it. That consolidated 1.5-2 hour nap in the middle of the day made a massive difference to night sleep. Research shows that during REM sleep, babies consolidate memories, regulate emotions, and boost their immune system—all crucial for development.
3. Earlier bedtime
Moving bedtime from 8 PM to 7 PM was counterintuitive—surely keeping them up longer would tire them out more? Nope. An overtired baby fights sleep harder. That earlier bedtime meant a calmer, easier settling process.
4. The “pause”
This was the hardest but most effective change. When our baby woke at night, instead of immediately rushing in, we’d pause for 30-60 seconds. Often, they’d resettle themselves. If not, we’d go in, but this pause helped them develop self-soothing skills.
5. Keeping feeds separate from sleep
We moved the bedtime feed earlier in the routine, so it wasn’t the last thing before sleep. This helped break the feed-to-sleep association.
What We’re Still Getting Wrong
Let’s be real—we haven’t figured everything out. Here are the ongoing challenges:
Early morning wakings:
Some mornings our baby is up at 5:30 AM, bright-eyed and ready for the day. We’re working on this by ensuring the room stays dark (blackout curtains are non-negotiable) and not engaging too much during those early wakes.
Nap transitions:
Just when we think we’ve nailed the nap schedule, our baby decides they need one fewer nap. These transitions are messy and exhausting.
Travel and visitors:
Any disruption to routine means 2-3 days of chaos afterwards. We’re learning to be more flexible while maintaining core elements like bedtime and the wind-down routine.
Teething:
When those teeth start coming through, all bets are off. Sleep regresses, night wakings increase, and we’re back to survival mode temporarily.
What We’re Trying Next
As our baby approaches 9 months, we’re working on:
Transitioning to two naps:
Our baby is showing signs they’re ready to drop that third cat nap. We’re gradually extending wake windows and watching for tired cues to time this right.
Extending night sleep:
Currently, we’re getting one wake-up per night (usually around 3-4 AM). We’re working with our pediatrician to determine if this is still a necessary feed or if it’s become habitual.
Addressing sleep associations:
We’re slowly reducing our presence at bedtime. Right now, we stay in the room until our baby is asleep. The plan is to gradually move towards the door over several weeks.
Maintaining flexibility:
We’re trying to hold the routine while also accepting that some days will be chaotic—and that’s okay. A missed nap or a later bedtime doesn’t undo all our hard work.
The Mistakes We Made (So You Don’t Have To)
Looking back, here are the things I wish we’d known from the start:
1. Starting the bedtime routine too late
Waiting until our baby showed tired signs meant they were already overtired. Starting the wind-down before those signs appeared made everything smoother.
2. Being too rigid
In the early weeks, we stressed about timing everything perfectly. Newborns need flexibility. Save the structured schedule for when they’re developmentally ready (around 3-4 months).
3. Not prioritising the sleep environment
We should have invested in blackout curtains and a quality white noise machine from day one. These environmental factors make a massive difference.
4. Comparing to other babies
Our friend’s baby slept through the night at 8 weeks. Ours didn’t. That’s completely normal. Every baby is different, and comparing only added stress.
5. Expecting linear progress
Sleep isn’t a straight line. Just when you think you’ve cracked it, a regression, illness, or developmental leap throws everything off course. That’s parenting.
6. Neglecting our own sleep
My partner and I were both trying to handle every wake-up, leaving us both exhausted. Taking shifts meant each of us got at least one stretch of uninterrupted sleep. This made us better parents.
The Real Talk: What “Success” Looks Like
Here’s what I want you to know: sleeping through the night doesn’t mean 12 hours of uninterrupted sleep. According to the Sleep Foundation, “sleeping through the night” for babies means a 6-8 hour stretch. Even babies who are considered “good sleepers” still wake briefly between sleep cycles—they just manage to resettle without calling for help.
At 8 months, our baby now:
- Goes to bed at 7 PM with minimal fuss
- Sleeps until 3-4 AM (a 8-9 hour stretch)
- Has one quick feed and goes back to sleep until 6:30-7 AM
- Takes two solid naps during the day
Is this perfect? No. Would I love a full night’s sleep? Absolutely. But compared to where we started—waking every 90 minutes—this feels like a miracle.
Your Journey Will Be Different (And That’s Okay)
If there’s one thing I’ve learned through this exhausting journey, it’s that there’s no perfect formula. The routine that works for us might not work for you. Your baby might be different, your family circumstances might be different, and that’s completely fine.
What matters is finding what works for your family and being willing to adapt when it doesn’t. Some nights will be great. Some will be disasters. Sleep regressions will happen. Teeth will come through. Illnesses will strike. And through it all, you’ll figure it out—just like we’re still figuring it out.
The goal isn’t perfection. It’s progress. It’s slightly more sleep this month than last month. It’s a bedtime routine that makes evenings less chaotic. It’s knowing that even on the hardest nights, you’re not alone in this.
If you’re in the thick of it right now, reading this while your baby refuses to sleep: you’re doing great. This phase is temporary. It gets easier. And one day (or so I’m told), you’ll actually miss these exhausting early months.
Or maybe not. Either way, you’ve got this.
